This paper provides a stylized model of the workings of a global economy where one of its key driving factors is economic agents' continuous struggle to find assets in which to park financial resources. This struggle naturally comes with euphoria and disappointments, as many of the "parking...

In this paper we document first that, in contrast with their widely perceived excess returns, popular carry trade strategies yield low systemic-risk-adjusted returns. In particular, we show that carry trade returns are highly correlated with the return of a VIX rolldown strategy — i.e., the...

One of the main economic villains before the crisis was the presence of large “global imbalances.” The concern was that the U.S. would experience a sudden stop of capital flows, which would unavoidably drag the world economy into a deep recession. However, when the crisis finally did come,...

Severe financial crises in developed economies are produced by a combination of three factors: negative surprises that create uncertainty, concentration of macroeconomic risk in leveraged financial institutions and a slow policy response. We propose a policy instrument, Tradable Insurance...

The world has a shortage of financial assets. Asset supply is having a hard time keeping up with the global demand for store of value and collateral by households, corporations, governments, insurance companies, and financial intermediaries more broadly. The equilibrium response of asset prices...

We present a model of flight to quality episodes that emphasizes systemic risk and the Knightian uncertainty surrounding these episodes. Agents make risk management decisions with incomplete knowledge. They understand their own shocks, but are uncertain of how correlated their shocks are with...

Three of the most important recent facts in global macroeconomics - the sustained rise in the US current account deficit, the stubborn decline in long run real rates, and the rise in the share of US assets in global portfolio - appear as anomalies from the perspective of conventional wisdom and...

We present a model of flight to quality episodes that emphasizes financial system risk and the Knightian uncertainty surrounding these episodes. In the model, agents are uncertain about the probability distribution of shocks in markets different from theirs, treating such uncertainty as...

In this paper we provide a model of the macroeconomic implications of safe asset shortages. In particular, we discuss the emergence of a deflationary safety trap equilibrium with high risk premia. It is an acute form of a liquidity trap, in which the shortage of a specific form of assets, safe...

During extreme financial crises, all of a sudden, the financial world that was once rife with profit opportunities for financial institutions (banks, for short), becomes exceedingly complex. Confusion and uncertainty follow, ravaging financial markets and triggering massive flight-to-quality...
